jmcneill e692a6c76a Introduce pmf_system_bus_resume. In the ACPI S3 resume path, use this to 
separate powering up devices from restoring their state. This is required
on some machines where AcpiLeaveSleepState can fail due to an attempt to
access a powered off device.

ad 7b8aa25abc Change the ncpu test to work when a pool_cache or softint is initialized 
between mi_cpu_attach() and attachment of the boot CPU. Suggested by mrg@.

lukem 961afe5035 use __KERNEL_RCSID() instead of __RCSID() 2007-12-11 12:16:34 +00:00

jmcneill 5bd9c210ef Use malloc/free instead of kmem_alloc/kmem_free in pmf_event_inject, since 
the latter is not safe to use from a softint. Pointed out by rmind.

configure() on some architectures.

elad 9725bcfd97 - Use KAUTH_ARG() instead of casts, 
- Don't ignore return value of settime() in sysctl_kern_rtc_offset(), as
  suggested by yamt@.

Note: the kauth(9) call in sysctl_kern_rtc_offset() is bogus, but this will
be addressed separately.

jmcneill 6829a93c1c Use aprint_debug to notify the user that a device does not implement the 
power management framework rather than aprint_error.

pooka db06a930e6 Remove cn_lwp from struct componentname. curlwp should be used 
from on.  The NDINIT() macro no longer takes the lwp parameter and
associates the credentials of the calling thread with the namei
structure.

okay yamt@.

ad e23d4a9b80 Nothing uses shared -> exclusive upgrades any more, so remove the code. 
This is good since they are effectively the same as ...

	lockmgr(&lock, LK_RELEASE);
	lockmgr(&lock, LK_EXCLUSIVE);

.. and therefore don't behave as expected.

rmind 6fcda0686a Increase the default limit of SEM_MAX, allow changing of limit 
dynamically via sysctl.  Closes PR/36979.

ad f2fb0b3870 mutex_init: use 'if' instead of 'switch' to avoid complaints from the 
compiler.
 2007-12-06 01:18:46 +00:00
pooka 4e38160d4d Do not "return 1" from kqfilter for errors. That value is passed 
directly to the userland caller and results in a mysterious EPERM.
Instead, return EINVAL or something else sensible depending on the
case.
 2007-12-05 17:19:46 +00:00
ad 598ab03ad0 Match the docs: MUTEX_DRIVER/SPIN are now only for porting code written 
for Solaris.
 2007-12-05 07:06:50 +00:00
ad 8cd835a351 pool_init, pool_cache_init: hack around IP input processing which can 
not yet safely block without severely confusing soo_write() and friends.
If the pool's IPL is IPL_SOFTNET, initialize the mutex at IPL_VM so that
it's a spinlock. To be dealt with correctly in the near future.

ad b21038696d mutex_init: make MUTEX_DEFAULT + IPL_SOFT* return an adaptive mutex. 2007-12-05 06:50:07 +00:00
mjf d4a648c345 Implement a new magic string for magic symlinks, @ruid, which exapnds to the 
real user id of the process and use this magic string for per-user tmp.
This should fix PR/35687

ad 27f20ecf58 Soft interrupts can now take proclist_lock, so there is no need to 
double-lock alllwp or allproc.

ad 9027344d32 For the slow path soft interrupts, arrange to have the priority of a 
borrowed user LWP raised into the 'kernel RT' range if the LWP sleeps
(which is unlikely).

ad 4b293a84e1 Interrupt handling changes, in discussion since February: 
- Reduce available SPL levels for hardware devices to none, vm, sched, high.
- Acquire kernel_lock only for interrupts at IPL_VM.
- Implement threaded soft interrupts.

christos 9e2c6405b0 kill a diagnostic for now. 2007-12-03 02:20:24 +00:00
christos 33cb8be1db - add an elf aux vector entry for implementing $ORIGIN. 
- the code to convert from a vnode to a path is commented out now until
  a better solution is implemented. Only absolute paths work for now
  (which is most of the cases).

ad 208085366c sys__lwp_create: set in the correct lock when the LWP is created suspended. 2007-12-02 15:49:38 +00:00
ad e2aaefb859 - mi_switch: adjust so that we don't have to hold the old LWP locked across 
context switch, since cpu_switchto() can be slow under certain conditions.
  From rmind@ with adjustments by me.
- lwpctl: allow LWPs to reregister instead of returning EINVAL. Just return
  their existing lwpctl user address.
 2007-12-02 14:55:32 +00:00
hannken d556dc98b0 Fscow_run(): add a flag "bool data_valid" to note still valid data. 
Buffers run through copy-on-write are marked B_COWDONE.  This condition
is valid until the buffer has run through bwrite() and gets cleared from
biodone().

Welcome to 4.99.39.
